Antarctic Protected Area Geological Mapping and Helicopter Landing Zones

Geological mapping at a 1:2000 scale covers a 400 km² ice-free region in East Antarctica's Vestfold Hills. The dataset provides evidence for managing Antarctic Specially Protected Area No. 143 (Marine Plain), including derived polygons for recommended helicopter landing zones. It was presented at the SCAR Open Science Conference in 2024 and originates from Australian Ocean Data Network sources.

Use Cases

• Delineate helicopter landing zones by applying buffers around the vulnerable Sørsdal Formation and lakes.
• Assess risks from foot traffic by analyzing surficial geology and geomorphology mapping of Marine Plain.
• Compare glacial sediment distribution across the Vestfold Hills region using the 1:2000 scale geological map.
• Support ASPA management plan revisions with evidence from aerial imagery, satellite data, and field observations.

Strengths

• Mapping covers a 400 km² ice-free region in the Vestfold Hills.
• Surficial geology was mapped at a detailed 1:2000 scale.
• Analysis is based on aerial photos, satellite imagery, digital elevation models, and field observations.

Limitations

• Specific row counts, column names, and dataset size are unknown.
• Data is presented in PDF and HTML formats, limiting direct machine analysis.
• Focus is restricted to a single ASPA (No. 143) and the surrounding Vestfold Hills region.
